EASTBOURNE, England (AP) -- Marion Bartoli of France has withdrawn from the Eastbourne grass-court tournament with a viral infection, giving No. 2-seeded Li Na of China a walkover into the quarterfinals.

Later Wednesday, 2012 runner-up Angelique Kerber of Germany was paired against 2010 champion Elena Makarova of Russia and Czech Petra Kvitova faced Yanina Wickmayer of Belgium.

In the men's draw, top-seeded Milos Raonic of Canada plays Croatia's Igor Dodig and second-seeded Gilles Simon of France plays Britain's Kyle Edmund.
